The Conitel 2020 protocol was developed by Leeds&Northrup for communication between a SCADA system and RTUs
of the same vendor.
Physical layer encoding is based on 32-bit words.
Conitel 2020 operates in half-duplex mode following the master/slave principle.
A master can communicate with up to 15 RTUs, an RTU only responds to explicit
requests by the master.
PCM, half-duplex, 32 bit data words
